I have been collecting Ha and OIII data for WR134 and trying various HOO blends of the form:
where: 0 < a < 1
None gave me the blue/gold blend I like initially and manipulation using SelectiveColor to get the color palette I like in Photoshop seemed to harshly degrade the fine strands of features in the jellyfish-like morphology of the object.
Instead I tried a different process I used once before.
I started by stretching the Ha and OIII in Pixinsight using the DeLinear script and then exporting each frame to Photoshop.
Then I used the GradientMap feature in PhotoShop to convert the Ha to a range of golden shades and the OIII to a range of bluish shades and blended the two layers using the "Linear Dodge (Add)" blending mode.
This gave me a nicer starting point and allowed me to manipulate the OIII/Blue color independently.
I need to play with it more but my initial attempt was more to my liking than my traditional HOO process:
